    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。  e]$s t?  
    3o/[t  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: +LJ73 !  
    enableservice('AutomationServer', true) @>7%qS  
    enableservice('AutomationServer') Y}KNKO;  
    MiX43Pk]  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 iH'p>s5L  
    G^@5H/)  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 9: lFo=  
    1. 在FRED脚本编辑界面找到参考. +aAc9'k   
    2. 找到Matlab Automation Server Type Library a$fnh3j[  
    3. 将名字改为MLAPP /BL4<T f

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 -$g#I

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |5]X| v  
    1. 创建Matlab服务器。 ,`sv1xwd  
    2. 移动探测面对于前一聚焦面的位置。 ?\n > AC  
    3. 在探测面追迹光线 3$ PV2"  
    4. 在探测面计算照度 HK% 7g  
    5. 使用PutWorkspaceData发送照度数据到Matlab 43 :X,\~)  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !d T4  
    7. 用Matlab画出照度数据 l}P=/#</T  
    8. 在Matlab计算照度平均值 _tycgq#  
    9. 返回数据到FRED中 Rk8P ax/JK
